scimitarf1 Posted March 23, 2018 Share Posted March 23, 2018 Slightly random question. Looking to get some wire to replicate and was wondering what the diameter of the real thing was. Any help much appreciated Will Link to comment Share on other sites More sharing options...
Rick Griewski Posted March 25, 2018 Share Posted March 25, 2018 I will assume that this is not an academic queation. I recommend that you identify the specific kit or resin engine and make a prototype or two of the loop on the engine. Decide the diameter of the wire by comparing the look of your loop relative to the front components of the engine. Look at a reference or two. I would then select the wire that looks good and the fabricate the loop out of styrene rod so you can drill small holes to attach the plug wires. Hope this helps, Rick Link to comment Share on other sites More sharing options...
Juggernut Posted March 25, 2018 Share Posted March 25, 2018 (edited) As a ballpark figure, the high tension leads on R-2800's (and many other engines) are approximately 0.5 inches (12.7 mm) in diameter (.02 inches in 1/32) give or take a fraction of an inch or two. So 0.020 or 0.025 wire will suffice. As Rick mentioned, I'd get a small sample of said diameter wire (or Evergreen styrene rod) and see how it looks. Sometimes actual measurements don't look correct when coupled with something else that may or may not be scaled exactly the same (even though it's supposed to be).

scimitarf1 Posted March 25, 2018 Author Share Posted March 25, 2018 Many thanks for that. I have found some.39mm braided brass wire that looks a little thin off the model but in terms of colour and look is spot on Link to comment Share on other sites More sharing options...

thierry laurent Posted March 30, 2018 Share Posted March 30, 2018 80/128...jeez! To me a little bit more than half a millimiter in 1/32 stays far more simple... ;-) TimHepplestone and Zero77 2 Link to comment Share on other sites More sharing options...
